ICE-PICK.

Application filed July 7, 1909.

To all whom it may concern:

Be it known that I, EMIL R SrALKn, a citizen of the United States,residing at Lawrence, in the county of Essex and State of Massachusetts,have invented new and useful Improvementsin Ice-Picks, of which thefollowing is a specification.

This invention is an improved ice pick having a split edge and apenetrating point PIOJQCUl'lg beyond the said edge as hereinafterdescribed and claimed, the object of the invention being to provide anice pick of the improved form which serves to split the ice and preventthe same from breaking up in a number of small pieces.

In the accompanying drawings :-Figure l is a side elevation of an icepick constructed in accordance with this invention. Fig.

2 is a similar view at rightangles to Fig. 1.

My improved ice pick comprises a chisellike blade 1 and a handle 2 atone end of the same. The outer or lower end of the blade is beveled onopposite sides as at 3 to form a wedge shaped splitting edge 4, thewidth of which is equal to that of the blade. The

blade is further formed with an inverted conical penetrating point 5which is disposed midway between the side edges of the splitting edgeand the said penetrating point projects beyond the center of thesplitting edge for a suitable distance and serves to enter the ice aheadof the splitting edge, to act as a guide for the splitting edge insplitting the ice. The conical penetrating point 5 is coincident withand extends across the center of the wedge-shaped splitting edge of theblade and the sides of the said penetrating point are more acute thanthose of the Specification of Letters Patent.

Serial No. 506,362.

I splitting edge so that the sides of the penel trating point convergewith those of the i splitting edge at the common base of the penetratingpoint and the splitting edge. In effect, the penetrating point forms aridge across the splitting edge. In the operation of the pick the saidpenetrating point exerts wedge or splitting action in the ice in advanceof the oppositely beveled splitting edge and thus the pick at a singlestroke into the ice exerts an initial splitting action by means of thepenetrating point and a final splitting action by means of the splittingedge with the result that the ice is split on a clean fracture and. isnot broken into a number of small pieces and hence my improved pickeffects a considerable economy the ice is being s lit.

\Vhat. is claimed is The herein described ice pick comprising achisellike blade having a wedge-shaped straight splitting edge and aconical point at one end, said edge and said point having a common base,the said splitting edge having beveled sides which lie at a slight,angle with reference to each other and converge to form a sharpenededge, and the said conical point projecting be 0nd the said splittingedge and longitu inally of the blade.

In testimon whereof I atfix my signature in presence 0 two witnesses.
